In software development, accurately measuring the size of a codebase is essential for project management, resource allocation, and progress tracking. However, traditional tools often include auto-generated and data files, such as package-lock.json, yarn.lock, and data.json, etc. in their line counts. This leads to inflated metrics because technically, you didn't add the lines of code by yourself. To address this challenge, I developed git-repo-lines-of-code, an open-source project designed to provide precise line counts by excluding specified files.
The Motivation Behind git-repo-lines-of-code
While tools like cloc are popular for counting lines of code, they don't offer straightforward mechanisms to exclude specific files or patterns, especially when dealing with auto-generated files that can skew the analysis. This limitation prompted the creation of a tool that allows developers and managers to:
- Exclude Unwanted Files: Omit files that do not contribute to the actual codebase, ensuring more accurate metrics.
- Automate the Counting Process: Eliminate the need for manual adjustments, reducing errors and saving time.
- Enhance Reusability: Provide a solution that is easily integrated into various projects and workflows.
How to Use git-repo-lines-of-code
To get started with git-repo-lines-of-code, follow these steps:
- Installation: Install the package globally using npm:
npm install -g git-repo-lines-of-code
- Basic Usage:
import getRepoLinesOfCode from 'git-repo-lines-of-code';
const owner = 'octocat';
const repo = 'Hello-World';
const excludeFilePaths = ['path-to-file.ts', 'path-to-auto-generated-code.json'];
getRepoLinesOfCode(owner, repo, excludeFilePaths)
.then((linesOfCode) => {
console.log(`Total lines of code: ${linesOfCode}`);
})
.catch((error) => {
console.error(`Error: ${error}`);
});
Running this function will execute the line count with the specified exclusions.
Conclusion
git-repo-lines-of-code offers a streamlined approach to accurately measuring your codebase by excluding non-essential files. Its flexibility and ease of use make it a valuable tool for developers and managers seeking precise code metrics.
The package is open-source, and contributions are welcome. You can access the npm package here and the GitHub repository here.
Please, feel free to explore, contribute, and integrate it into your projects to maintain accurate code metrics.
Happy coding!

How to work with dates and times in js?
Jul 01, 2025 am 01:27 AM
The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
